DETAILED DESCRIPTION

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 and 2 As shown, the present embodiment discloses a high-altitude fixed infrared level pay-out bracket, comprising a sleeve 1, one end of which is fixed with two hook-shaped portions 2, the two hook-shaped portions 2 are fixed to a vertically arranged rotating sleeve 3 on the side away from the sleeve 1, a rotating shaft 4 is rotatably connected in the rotating sleeve 3, both ends of the rotating shaft 4 are fixed to a triangular bracket 5, and the triangular bracket 5 is provided with a connecting support 6 for fixing the level.

[0020] The sleeve 1 has a threaded through hole inside, and a screw rod 7 is connected to the inner thread of the sleeve 1. The screw rod 7 is rotatably connected to an arc plate 8 at one end close to the hook portion 2. A connecting head 9 is provided at the end of the screw rod 7 away from the hook portion 2. The connecting head 9 is fixedly connected to the screw rod 7, and the other end is rotatably connected to a movable crank 10.

[0021] A plurality of convex teeth 11 are arranged in a ring shape around the axis of the sleeve 1 on the outer wall of the sleeve 1 near one end of the movable crank 10; a clamping sleeve 12 is sleeved on the sleeve 1, and a plurality of tooth grooves 13 are arranged in a ring shape around the axis of the clamping sleeve 12 on the inner wall of the clamping sleeve 12, the tooth grooves 13 are slidably engaged with the convex teeth 11, and rings 14 are fixed side by side on the outer wall of the clamping sleeve 12.

[0022] When the utility model is used, the inner sides of the two hook-shaped portions 2 are sleeved on the scaffolding steel pipe and are close to the outer wall of the steel pipe, and the movable crank 10 is rotated at the same time to control the screw rod 7 and drive the arc plate 8 to be pressed against the scaffolding steel pipe, and then the movable crank 10 is rotated inwardly so that the movable crank 10 and the screw rod 7 are arranged side by side, and the clamping sleeve 12 is rotated so that the ring 14 on the clamping sleeve 12 is opposite to the movable crank 10, and the clamping sleeve 12 is axially slid to cooperate with the convex teeth 11 through the tooth groove 13, so that the clamping sleeve 12 is clamped on the sleeve 1, and the ring 14 is sleeved on the movable crank 10, so that the rotation of the screw rod 7 is limited by limiting the position of the movable crank 10.

[0023] In this embodiment, an anti-falling rope 15 is connected to the sleeve 1, and a hanging ring 16 is provided on the anti-falling rope 15. The hanging ring 16 can be hung on the horizontal steel pipe on the scaffold to prevent the whole from falling.

[0024] In this embodiment, connecting rods 17 are provided at the ends of the two hook-shaped portions 2 , and the ends of the connecting rods 17 are fixed to the hook-shaped portions 2 to improve the structural strength of the hook-shaped portions 2 .

[0025] In this embodiment, a top screw 18 is threadedly connected to the rotating sleeve 3, and the inner end of the top screw 18 is against the rotating shaft 4. When the triangular bracket 5 is rotated to a suitable position, it can be fixed by the top screw 18.

[0026] It should be noted that in the background technology, a simple laser level fixing bracket is disclosed in the Chinese utility model patent application number CN202221503069.2, and the support structure for fixing the level is described in detail in its specification. The connecting support 6 in this embodiment can adopt the structure in the patent.

[0027] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
